Use meaningful exit codes change "source" to "cat" to view output instead of assigning Show Sample Output
-1source <(egrep '^#define EX_.*' /usr/include/sysexits.h | sed -e 's/#define/declare -r/g' | sed 's/\//#/g' | sed -e 's/\s\{1,\}/ /g' | sed -e 's/ \([0-9]\)/\=\1/'g ) -
Given a dump.sql file, extract table1 creation and data commands. table2 is the one following table1 in the dump file. You can also use the same idea to extract several consecutive tables.
-1cat dump.sql | sed -n -e '/Table structure for table .table1./,/Table structure for table .table2./p' -
-1sed -i 's/http:\/\/old\/new\///g' index.html

Quickly remove the conflicting line (key) from current users known_hosts file when there is an SSH host conflict. Very nice when you get tired of writing out full commands. Ideally you would place this into your .bash_profile Usage: rhost [n] Example: rhost 33 (removes line 33 from ~/.ssh/known_hosts) Function assumes the $HOME exists, you could alternatively use "~/.ssh/known_hosts" Mac OSX likes a space for sed -i "$1" d
-1rhost() { if [[ $1 =~ ^[0-9]+$ ]]; then sed -i "$1"d ${HOME}/.ssh/known_hosts; else echo "rhost [n]"; fi } -
-1ls --color=never -1| grep -E "[0-9]{4}"|sed -re "s/^(.*)([0-9]{4})(.*)$/\2 \1\2\3/" | sort -r

Find and replace specific characters in a single line in multiple files with sed. Show Sample Output

"seq" has an additional parameter to use as INCREMENT. # seq FIRST INCREMENT LAST https://linux.die.net/man/1/seq Show Sample Output
-1for i in $(seq 1 5) ; do echo $i ; done -
Allows for quick mass renaming, assuming the user has some familiarity with regular expressions. Basically, it replaces the original_file_name in the output of ls with "mv -v original_file_name new_file_name" and passes the output to sh. Show Sample Output
-2ls /some/directory | sed -rn -e 's/input_file_regex/mv -v & output_file_name/p' | sh -
ok I'm sure it's not pretty Show Sample Output

For this example, all files in the current directory that end in '.xml.skippy' will have the '.skippy' removed from their names.
-2for f in $(ls *.xml.skippy); do mv $f `echo $f | sed 's|.skippy||'`; done -
It's not a big line, and it *may not* work for everybody, I guess it depends on the detail of access_log configuration in your httpd.conf. I use it as a prerotate command for logrotate in httpd section so it executes before access_log rotation, everyday at midnight.
-2cat /var/log/httpd/access_log | grep q= | awk '{print $11}' | awk -F 'q=' '{print $2}' | sed 's/+/ /g;s/%22/"/g;s/q=//' | cut -d "&" -f 1 | mail youremail@isp.com -s "[your-site] search strings for `date`" -

Here's a version that doesn't use find.
-2ls -rl --time-style=+%s * | sed '/^$/,/^total [0-9]*$/d' | sort -nk6 -
Instead of having someone else read you the Digg headlines, Have OSX do it. Requires Curl+Sed+Say. This could probably be easily modified to use espeak for Linux.
-2IFS=`echo -en "\n\b"`; for i in $(curl http://feeds.digg.com/digg/container/technology/popular.rss | grep '<title>' | sed -e 's#<[^>]*>##g' | tail -n10); do echo $i; echo $i | sed 's/^/Did you hear about /g' | say; sleep 30; done -

Broaden your knowledge of the utilities available to you in no particular order whatsoever! Then use that knowledge to create more nifty one-liners that you can post here. =p Takes a random number modulo the number of files in $dir, prints the filename corresponding to that number, and passes it as an argument to man.
-2dir="/bin"; man $(ls $dir |sed -n "$(echo $(( $RANDOM % $(ls $dir |wc -l | awk "{ print $1; }" ) + 1 )) )p") -
Great idea camocrazed. Another twist would be to display a different man page based on the day of the year. The following will continuously cycle through all man pages:
man $(ls /bin | sed -n $(($(date +%j) % $(ls /bin | wc -l)))p)-2man $(ls /bin | sed -n $((RANDOM % $(ls /bin | wc -l) + 1))p) -

an extension of command 9986 by c3w, allows for link text. http://google.com,search engine will link the hyperlink with the text after the url instead of linking with the url as linktext Show Sample Output
-2sed "s/\([a-zA-Z]*\:\/\/[^,]*\),\(.*\)/\<a href=\"\1\"\>\2\<\/a\>/" -
